Abstract: A plastic netting in the form of a raschel netting (2) for the cultivation and harvest of onions. The plastic netting has a plurality of pillar stitches (1) extending mutually in parallel in the longitudinal direction. These pillar stitches are transversely interlinked by traversing weft threads (4). Each pillar stitch (1) being formed by at least two threads (2, 3).

Abstract: A packaging material (600) comprises a first sheet material (100) and a woven fabric (200), which are arranged one above the other and are connected to one another. The first sheet material (100) contains first regions (120), in which the first sheet material (100) is expanded locally, and second regions (110), in which the first sheet material (100) is not expanded locally. The first regions (120) are arranged in each case between two second regions (110) and run in a first direction. The woven fabric (200) comprises a thread (220), wherein part of the thread (220) runs in a direction which intersects the first direction.

Abstract: A Raschel machine (100) comprises a plurality of first guide needles (110) arranged along a first direction for guiding warp threads (210), a plurality of second guide needles (150) arranged along the first direction for guiding weft threads (220) and a plurality of needles (180) arranged along the first direction for creating interlocked loops formed by threads, whereby the warp threads (210) are created. The first guide needles (110) are held by a first needle bar (120), the second guide needles (150) are held by a second needle bar (160), and the second needle bar (160) is moved back and forth between two respective neighbouring first guide needles (110). The space between neighbouring first guide needles (110) is greater than 25.4 m (1 inch).

Abstract: The invention relates to a plastic mesh having a plurality of chains extending parallel to one another in a longitudinal direction, which plastic mesh has a plurality of groups of chains (2) adjacent to one another, which are in each case formed of at least two chains (2a, 2b). The groups of chains (2) have a greater spacing relative to one another or also relative to a further individual chain (1) than the chains (2a, 2b) within a group of chains (2). A thread (3) runs in a zigzag between two adjacent groups of chains (2) or also between one group of chains (2) and an individual chain (1) and connects the chains (1) or groups of chains (2).

Abstract: A method, an elongating device, a Raschel knitting machine comprising the elongating device for producing nets with elongated stitches and a net comprising elongated stitches is described. The method comprises the steps of continuously generating new loops for elongating the two rows of loops by additional loops and dragging the rows of loops in a machine direction, generating a first stitch of the weft by joining the weft to a loop of the first row and to a loop of the second row, and positioning the first stitch across a surface of an elongating device for preventing the first stitch from traveling with the warps knitted to loops in the machine direction. The joining is configured for elongating the first stitch by pulling additional weft material, and the surface of the elongating device is carrying out a reciprocating movement towards the first stitch. Further, an elongating device for elongating of the stitches is described.

Abstract: This invention relates to a packaging bag. The packaging bag is made of an envelope of at least one enclosing element made of polymer material and the envelope includes a plurality of perforation holes at least on a part of the enclosing element. The packaging bag is especially suited for accommodating goods which have damageable surfaces and require air ventilation. Such goods may be agricultural products.

Abstract: By the extrusion method, (position 1) polyethylene yarns are produced (position 2). These yarns are cooled in a cold water container (position 3). Following that and after having been pre-stretched (position 4), the yarns come into a heating oven (position 5), where they are drawn by shafts (position 6). The monofilament that has been created by the method is then coiled in bobbins (position 8) through an appropriate coiling system (position 9). Following that, the monofilament bobbins are placed on the Raschel knitting machine and are knitted together with polyethylene yarns in latticed fabric. The final product shall be a net utilized for the palletization of various materials. This net has high elasticity, extensibility and breaking resistance.
